1I Claim.

, Thisfrinventionirelates toiai novel andimprovedi sidebearingand-.consistsof the'. matters hereinafte'iidescribed andmoreparticularly pointed out in the appended claim.

The object of the invention is to produce a novel and improved form ofside bearing, including a roller casing and filler plate constructed andarranged for use with shims for vertical adjustment of the fill plate,with no-vel means for retaining the iiller plate and shims in positionwhen mounted on a bolster, but permitting ready access to said shims forinsertion, removal or replacement, to vary the level of the fillerplate.

In the drawings:-

l5 Figure 1 is a view representing a top plan of the improved sidebearing;

Figure 2 is a side elevation of the side bearing with parts shown invertical section as indicated by the line 2 2 of Figure 1; 2O Figure 3is an end View of the side bearing with parts shown in vertical section;

Figure 4 is a partial perspective view of an end of the casing with theplate and shim retaining member removed and in vertical position abovethe place which it is to occupy when in position on the end of thecasing; and

Figure 5 is a like view but showing said plate and shim retaining memberin proper position and secured to the end of the casing. 30 In thedrawingsz-IU indicates the casing and II indicates the ller plate, whichalso constitutes the wear plate. I2 indicates the antifriction rollerand I3, I3 indicate shims located below the ller plata-it beingunderstood, of course, that the casing and shims rest directly on thebolster.

The casing III is a hollow shell, open top and bottom, and provided withlaterally extending apertured lugs I4 at the base for attachment to 40the bolster by means of bolts or lag screws,-in a familiar manner. Thecasing has side walls I5,

I5 and end walls I6, I'I. In the side walls are formed horizontal waysVor vchannels I8, in which travel short studs I 9 on the ends of theroller and 45 co-axial therewith. Said ways or channels extend in eachdirection from the middle of the casing a distance suicient to provideaccommodation for the designed travel of the roller.

The combined wear plate and ller block I I is 50 loose in the casing andis of a familiar form, in

the main having a wear surface 2U inclined in opposite directions from atransverse median line for the purpose of centering the roller andhaving transverse bottom ribs 2I, one at the middle 55 and one at eachend, which present bearings or rests? forthe ller block 'for supporting:engagement' against' the bolster 'orf the shirnsinterposedAbetween-said'ibolster and `the saidribsz` Horizontal ribs I5a, I5a onthe side walls and IGa, I'Ia on the end walls, limit the verticalmovement of the 5 ller block in the casing, said ller block looselytting within the sides and ends of the casing below said ribs, so as tobe movable therein for vertical adjustment by insertion or removal ofone or more shims between the bottom of said wear 10 plate and thebolster.

On the end wall I'I and projecting therefrom, is a` tting 22, preferablymade integral with said casing. 23 indicates a downwardly tapered studprovided throughout the greater part of its length l5 with flat lateralflanges 24, 24 and a top flange 25 extending at right angles to saidlateral anges.

The iitting 22 is provided with a way 22a between the proximate surfaceof the end wall I'I of the casing, as shown in Figure 4. This way issimilar in transverse and vertical section to that of the stud, with itslateral flanges 24 so that the stud 23 may be dropped into the way,being arrested in its downward movement by the horizontal top flange 25,which acts as a stop to en- 25 gage the horizontal top end 22h of thefitting 22. When in this position, the bottom end 23a, of the studprojects below the bottom plane of the casing I0, as clearly shown inFigures 2, 3 and 5, to engage with one of the usual holes or openings 26generally provided in the top plate of the car truck bolster 26a forattachment to side bearings of different designs. For easy access tosaid hole, said bottom end part 23a of the stud is slightly more taperedthan the main body of the stud.

A transverse groove 23b is formed in the stud intermediate its ends. Thefitting 22 is formed to provide a cylindrical hole or opening 21extending horizontally and intersecting the part of the way whichreceives the stud, so that a bolt 28 inserted through said hole willengage the groove 23h in the stud and act to lock said stud in the tting22.

The end wall I1 of the casing terminates con- 45 siderably above theplane of the bottom of the casing to leave a transverse opening I'Ibextending the full width of the casing. Into this opening extend theshims I3, as shown in Figure 2, said shims being longer than the wearplate, as shown in Figures 2 and 3. It will be observed that thisopening is blocked when the stud 23 is in nal position in the tting 22.When the bearing is rst assembled, ready for attachment to the bolster,one or more shims I3 may be in- 55 serted with thelwear plate II throughthe openingin the bottom of. the casing. After the casing is bolted tothe bolster, further adjustmentv of the vertical position of the Wearplate lll mayV locked in position by ther bolt 28.V

After the bearing has been in use and begins to show wear, it is Va,verysirnple operationy to remove the stud 23 in the Imanner describedand insert an additional shim o-r'shims, as required.

The construction described isvery simple'and ecient, is readily capableof economicalmanufacture and easy adjustment' to .rtake'up or providefor wear.
